The auxiliary installation fixture includes a first mounting beam, a second mounting beam, a trolley beam, a trolley, and lifting slings. The trolley beam is connected to a middle-layer bracket via the first mounting beam, and simultaneously connected to a frame via the second mounting beam, thus achieving fixed installation of the trolley beam.

Description

Technical Field

[0001] This invention relates to the technical field of auxiliary installation, and more particularly to an auxiliary installation tool and a method for using the auxiliary installation tool. Background Technology

[0002] Taking the SCE920 engine assembly as an example, the SCE920 engine assembly consists of the SCE920 engine body, shock absorber 100, frame 200, and intermediate bracket 300. The SCE920 engine body is a marine low-speed engine with a cylinder diameter of 920 mm. The frame 100 serves as the basic load-bearing component, and the frame 200 is arranged vertically. The SCE920 engine body is fixedly mounted on the frame 200. The intermediate bracket 300 is arranged horizontally and is also connected to the frame 200. Thus, the main plane of the intermediate bracket 300 is perpendicular to the main plane of the frame 200. This allows the frame 200 to mainly bear the weight of the SCE920 engine body and the vertical load, while the horizontal intermediate bracket 300 provides a stable horizontal support surface from the side for installing various accessories or connecting other components, thereby improving the overall structural strength and optimizing the spatial layout and functional integration.

[0003] However, the installation of the shock absorber 100 on the SCE920 engine assembly is a first-time operation with no prior experience. The installation method and specific load-bearing and transporting mechanism are still technical gaps. Furthermore, the shock absorber 100 can only be installed in the complete engine state. Due to the limitations of the overall structure of the SCE920 engine assembly and the layout of the specific installation area, it is not possible to use an independent load-bearing and transporting mechanism to assist in the movement and installation of the shock absorber 100. Therefore, it is necessary to consider a safe, stable, and convenient auxiliary installation tool to assist in the installation of the shock absorber 100 onto the SCE920 engine assembly. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary installation tool and a method for using the auxiliary installation tool, which enables the auxiliary shock absorber to be installed onto the engine assembly safely, stably and conveniently.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An auxiliary installation fixture is used to assist in the installation of a shock absorber onto an engine assembly. The engine assembly includes a frame and a middle support. The auxiliary installation fixture includes a first mounting beam, a second mounting beam, a trolley beam, a trolley, and a lifting sling. The trolley beam is connected to the middle support via the first mounting beam, and the trolley beam is connected to the frame via the second mounting beam. The trolley is slidably disposed on the trolley beam and is movable along the extension direction of the trolley beam. One end of the lifting sling is connected to the trolley, and the other end of the lifting sling is connected to the shock absorber.

[0007] As an optional solution for the auxiliary installation fixture provided by the present invention, the trolley beam is connected to the first mounting beam and one end of the first mounting beam is connected to the middle bracket; the trolley beam is connected to the second mounting beam and one end of the second mounting beam is connected to the frame.

[0008] As an optional solution for the auxiliary installation fixture provided by the present invention, one end of the first installation beam is connected to the middle layer bracket, the other end of the first installation beam is connected to the side wall of the second installation beam near the end, and the end of the second installation beam away from the first installation beam is connected to the frame.

[0009] As an optional solution for the auxiliary installation fixture provided by the present invention, multiple first installation beams and multiple second installation beams are provided. The number of first installation beams and second installation beams is the same and they correspond one-to-one. Multiple second installation beams are connected above the trolley beam.

[0010] As an optional solution to the auxiliary installation fixture provided by the present invention, the auxiliary installation fixture further includes a first connecting beam, the two ends of which are respectively connected to two adjacent second installation beams.

[0011] As an optional solution for the auxiliary installation fixture provided by the present invention, in the direction perpendicular to the frame away from the frame, the first connecting beam and the first mounting beam are connected to the second mounting beam at intervals, and the first connecting beam is located between the first mounting beam and the frame.

[0012] As an optional solution for the auxiliary installation fixture provided by the present invention, in the direction perpendicular to the frame away from the frame, the first connecting beam, the trolley beam and the first mounting beam are connected at intervals to the second mounting beam, and the trolley beam is located between the first connecting beam and the first mounting beam.

[0013] As an optional solution for the auxiliary installation fixture provided by the present invention, the auxiliary installation fixture further includes a third installation beam, one end of which is connected to the middle bracket, and the other end of which is connected to the trolley beam.

[0014] As an optional solution for the auxiliary installation fixture provided by the present invention, the trolley beam is an I-beam.

[0015] Secondly, the present invention also provides a method for using an auxiliary installation fixture, which is applied to the auxiliary installation fixture, and the steps include:

[0016] S1. The trolley beam is connected to the middle bracket via the first mounting beam, and the trolley beam is connected to the frame via the second mounting beam;

[0017] S2. Slide the trolley onto the trolley beam;

[0018] S3. Connect one end of the sling to the pulley and the other end of the sling to the shock absorber;

[0019] S4. Move the shock absorber to the target installation position of the engine assembly using a pulley and perform the installation operation.

[0020] The beneficial effects of this invention are:

[0021] The auxiliary installation fixture includes a first mounting beam, a second mounting beam, a trolley beam, a trolley, and lifting slings. The trolley beam is connected to the middle bracket via the first mounting beam and to the frame via the second mounting beam, thus achieving a fixed installation of the trolley beam. The trolley is slidably mounted on the trolley beam and can move along the extension direction of the trolley beam. One end of the lifting sling is connected to the trolley, and the other end can be connected to the shock absorber. This allows the shock absorber to be moved safely and stably along the extension direction of the trolley beam by the lifting sling. When the trolley moves the shock absorber to the target installation position of the engine assembly, the shock absorber can be installed. This can be done without the need for an additional independent load-bearing and transporting mechanism to complete the movement and positioning of the shock absorber. The auxiliary installation fixture operates more safely, stably, and conveniently. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0035] The SCE920 engine assembly consists of four core parts: the SCE920 engine body (i.e., a marine low-speed engine with a cylinder bore of 920 mm), the shock absorber 100, the frame 200, and the intermediate bracket 300. The frame 200, as the basic load-bearing component, is vertically arranged. The intermediate bracket 300 is horizontally arranged and fixedly connected to the frame 200. The main plane of the intermediate bracket 300 is perpendicular to the main plane of the frame 200, allowing the frame 200 to primarily bear the weight of the SCE920 engine body and vertical loads. The horizontal intermediate bracket 300 provides a stable horizontal support surface from the side, used for installing various accessories or connecting other components, thereby improving the overall structural strength and optimizing the spatial layout and functional integration. However, there are significant technological gaps in the installation of the shock absorber 100 in the existing technology. There are three main reasons for this. First, the installation of the shock absorber 100 is a first-time operation; there are no relevant process flows or experience data to refer to within the industry or on the production site, making it a process challenge starting from scratch. Second, the installation of the shock absorber 100 can only be carried out when the SCE920 engine assembly is fully assembled. This means that other components (such as the frame 200, the intermediate bracket 300, and the SCE920 engine body) are already in place, and the available installation space is basically occupied, making it impossible to create additional operating space by disassembling or adjusting the structure. Finally, due to the overall structural limitations of the SCE920 engine assembly (such as the longitudinal height of the frame 200, the horizontal extension length of the middle bracket 300, and the narrowness of the preset installation position of the shock absorber 100) and the physical layout of the specific installation area (such as surrounding pipelines, lifting lugs, reinforcing ribs, and other interferences), conventional independent load-bearing and transporting mechanisms (such as separate trolleys, lifting platforms, or robotic arms) cannot enter this area or complete the precise movement and positioning of the shock absorber 100. Therefore, a safe, stable, and convenient auxiliary installation tooling is urgently needed to assist in the installation of the shock absorber 100 onto the SCE920 engine assembly.

[0036] Therefore, in order to safely, stably, and conveniently install the shock absorber 100 onto the SCE920 engine assembly, such as... Figures 1 to 6 As shown, the present invention proposes an auxiliary installation fixture for assisting in the installation of a shock absorber 100 onto an engine assembly. The engine assembly includes a frame 200 and a mid-level bracket 300. The auxiliary installation fixture includes a first mounting beam 1, a second mounting beam 2, a trolley beam 3, a trolley 4, and a lifting sling 5. The trolley beam 3 is connected to the mid-level bracket 300 via the first mounting beam 1, and the trolley beam 3 is connected to the frame 200 via the second mounting beam 2. The trolley 4 is slidably disposed on the trolley beam 3 and can move along the extension direction of the trolley beam 3. One end of the lifting sling 5 is connected to the trolley 4, and the other end of the lifting sling 5 can be connected to the shock absorber 100.

[0037] Understandably, the auxiliary installation fixture is designed to assist in installing the shock absorber 100 onto the engine assembly, which is the SCE920 engine assembly. The SCE920 engine assembly includes the SCE920 engine body, the shock absorber 100, the frame 200, and the intermediate bracket 300. The frame 200, as a basic load-bearing component, is arranged vertically, while the intermediate bracket 300 is arranged horizontally and fixedly connected to the frame 200. The main plane of the intermediate bracket 300 is parallel to the frame 200. The main planes are perpendicular to each other, so that the frame 200 mainly bears the weight of the SCE920 engine body and the vertical load, while the horizontal intermediate bracket 300 provides a stable horizontal support surface from the side for installing various accessories or connecting other components. The auxiliary installation fixture proposed in this invention includes a first mounting beam 1, a second mounting beam 2, a trolley beam 3, a trolley 4, and a lifting sling 5. The trolley beam 3 is connected to the intermediate bracket 300 through the first mounting beam 1, so that the trolley beam 3 can be connected to the intermediate bracket 300 by means of the first mounting beam 1. The frame 300 is used, and the trolley beam 3 is connected to the frame 200 via the second mounting beam 2, so that the trolley beam 3 can be connected to the frame 200 via the second mounting beam 2, thereby achieving the fixed installation of the trolley beam 3. That is, the auxiliary installation fixture of the present invention uses the frame 200 and the middle bracket 300 of the SCE920 engine assembly to achieve the fixed installation of the trolley beam 3. Then, the trolley 4 is slidably set on the trolley beam 3 and the trolley 4 can move along the extension direction of the trolley beam 3. On this basis, one end of the lifting sling 5 is connected to the trolley 4, and the lifting sling 5... The other end of 5 can be connected to the shock absorber 100, so that the shock absorber 100 can be moved safely, stably and conveniently along the extension direction of the trolley beam 3 by the sling 5 and the trolley 4. When the trolley 4 moves the shock absorber 100 to the target installation position of the SCE920 engine assembly, the installation operation of the shock absorber 100 can be carried out. It can complete the movement and positioning of the shock absorber 100 without the need for an additional independent load-bearing and transporting mechanism, and at the same time, the operation of the auxiliary installation tooling is safer, more stable and more convenient.

[0038] It should be noted that the specific positions of the first mounting beam 1 connected to the middle bracket 300 and the second mounting beam 2 connected to the frame 200 are adjusted by those skilled in the art based on the specific dimensions of the first mounting beam 1 and the second mounting beam 2 and the adaptability to the weight of the shock absorber 100. Furthermore, the specific methods of connecting the first mounting beam 1 to the middle bracket 300 and the second mounting beam 2 to the frame 200 can be detachable connections such as multiple bolt connections or pin connections, i.e. Figures 1 to 4The connection method shown can also be other connection methods. Of course, it is also possible to integrate the first mounting beam 1 to the middle bracket 300 and the second mounting beam 2 to the frame 200. It should be noted that when connecting the first mounting beam 1 and the second mounting beam 2, connecting blocks can be set at corresponding positions on the middle bracket 300 and the frame 200. For example, connecting blocks can be welded at the position where the first mounting beam 1 connects to the middle bracket 300 and the position where the second mounting beam 2 connects to the frame 200. Threaded holes for bolts and pin holes for pins can be opened on the connecting blocks. Therefore, the connecting blocks can avoid weakening the original structural strength of the middle bracket 300 and the frame 200 caused by directly connecting the first mounting beam 1 and the second mounting beam 2 on the middle bracket 300 and the frame 200. At the same time, the connecting blocks, as local reinforcements, can effectively disperse the preload of bolts and pins and reduce stress concentration. In addition, the trolley 4 is slidably mounted on the trolley beam 3 and can move along the extension direction of the trolley beam 3. One end of the sling 5 is connected to the trolley 4 and the other end of the sling 5 is connected to the shock absorber 100. The sling 5 is existing technology and is not limited in detail here. It can be, for example, a wire rope, a chain, etc., to realize the connection between the shock absorber 100 and the trolley 4, so that the shock absorber 100 can be moved by the trolley 4.

[0039] Alternatively, in one embodiment, the trolley beam 3 is connected to the first mounting beam 1 and one end of the first mounting beam 1 is connected to the middle bracket 300; the trolley beam 3 is connected to the second mounting beam 2 and one end of the second mounting beam 2 is connected to the frame 200.

[0040] It is understandable that the first mounting beam 1 and the second mounting beam 2 are simultaneously connected to the trolley beam 3. That is, the trolley beam 3 is directly connected to the first mounting beam 1 and one end of the first mounting beam 1 is connected to the middle bracket 300. The trolley beam 3 is also directly connected to the second mounting beam 2 and one end of the second mounting beam 2 is connected to the frame 200. This allows the trolley beam 3 to be fixed by the frame 200 and the middle bracket 300, so that the shock absorber 100 can be moved safely, stably and conveniently along the extension direction of the trolley beam 3 by the lifting sling 5 and the trolley 4. When the trolley 4 moves the shock absorber 100 to the target installation position of the SCE920 engine assembly, the installation operation of the shock absorber 100 can be performed, while ensuring that the structure of the auxiliary installation tooling is simpler.

[0041] As a preferred option, such as Figures 1 to 4 As shown, one end of the first mounting beam 1 is connected to the middle bracket 300, the other end of the first mounting beam 1 is connected to the side wall of the second mounting beam 2 near the end, and the end of the second mounting beam 2 away from the first mounting beam 1 is connected to the frame 200.

[0042] It is understood that in this embodiment, the first mounting beam 1 is not directly connected to the trolley beam 3. Instead, one end of the first mounting beam 1 is connected to the middle layer bracket 300, and the other end of the first mounting beam 1 is connected to the side wall of the second mounting beam 2 near its end. At the same time, the end of the second mounting beam 2 away from the first mounting beam 1 is connected to the frame 200, so that the first mounting beam 1 and the trolley beam 3 are indirectly connected through the second mounting beam 2. Figure 2 The first mounting beam 1 and the trolley beam 3 shown are respectively connected to both sides of the second mounting beam 2, which improves the overall structural rigidity of the first mounting beam 1, the second mounting beam 2, and the trolley beam 3. Specifically, the transition through the second mounting beam 2 reduces the number of connecting structures on the trolley beam 3, thereby buffering the stress during the movement of the trolley 4 on the trolley beam 3. This avoids stress concentration or jamming problems caused by direct connection between the first mounting beam 1 and the trolley beam 3, thus improving the ease of assembly, smooth operation, and long service life of the auxiliary installation fixture. It should be noted that the specific connection method between the first mounting beam 1 and the second mounting beam 2 can be an integrated connection, a detachable connection, etc. Taking a detachable connection as an example, the connection between the first mounting beam 1 and the second mounting beam 2 is made by multiple bolts, pins, etc., which are not specified in detail here.

[0043] Furthermore, in this embodiment, as Figures 1 to 4 As shown, there are multiple first mounting beams 1 and multiple second mounting beams 2. The number of first mounting beams 1 and second mounting beams 2 are the same and correspond one-to-one. All of the multiple second mounting beams 2 are connected above the trolley beam 3.

[0044] It is understood that multiple first mounting beams 1 and second mounting beams 2 are provided, with the same number of first mounting beams 1 and second mounting beams 2 in a one-to-one correspondence. All of the multiple second mounting beams 2 are connected above the trolley beam 3, allowing the auxiliary installation fixture to be connected to the middle-layer bracket 300 via multiple first mounting beams 1. Furthermore, each of the multiple first mounting beams 1 is connected to a second mounting beam 2, thus connecting to both the frame 200 and the trolley beam 3. In other words, this embodiment, by providing multiple first mounting beams 1 and multiple second mounting beams 2, can improve the load-bearing capacity and overall rigidity of the auxiliary installation fixture, thereby enhancing its structural reliability. It should be noted that the specific number of first mounting beams 1 and second mounting beams 2 can be as follows: Figures 1 to 4 The two first mounting beams 1 and the two second mounting beams 2 shown correspond one-to-one, but other quantities are also possible. These are all adaptive adjustments made by those skilled in the art according to actual usage needs, and are not limited in detail here.

[0045] Furthermore, in this embodiment, as Figures 1 to 4 As shown, the auxiliary installation fixture also includes a first connecting beam 6, the two ends of which are respectively connected to two adjacent second installation beams 2.

[0046] It is understandable that when multiple first mounting beams 1 and second mounting beams 2 are provided, in order to further improve the structural strength and operational stability of the auxiliary installation fixture, and thus improve the auxiliary installation effect of the shock absorber 100, the auxiliary installation fixture in this embodiment also includes a first connecting beam 6. The two ends of the first connecting beam 6 are respectively connected to two adjacent second mounting beams 2, so that multiple second mounting beams 2 can be connected through the first connecting beam 6, thereby improving the structural strength and operational stability of the auxiliary installation fixture, and thus improving the auxiliary installation effect of the shock absorber 100. It should be noted that the specific number of first connecting beams 6 varies depending on the specific number of second mounting beams 2. Figures 1 to 4 For example, when there are two second mounting beams 2, only one first connecting beam 6 is provided to connect the two second mounting beams 2 respectively. Furthermore, when there are three second mounting beams 2, two first connecting beams 6 are provided, each located between two adjacent second mounting beams 2 for connection. Details will not be elaborated here. Additionally, the specific connection method between the first connecting beam 6 and the second mounting beam 2 can be an integrated connection, a detachable connection, etc. Taking an integrated connection as an example, the two ends of the first connecting beam 6 can be welded to two adjacent second mounting beams 2 respectively. Taking a detachable connection as an example, the two ends of the first connecting beam 6 can be connected to two adjacent second mounting beams 2 respectively using multiple bolts, pins, etc. These are all adaptive choices made by those skilled in the art based on actual usage requirements, and are not limited in detail here.

[0047] Optionally, the auxiliary installation fixture also includes a second connecting beam, the two ends of which are respectively connected to two adjacent first installation beams 1.

[0048] It is understandable that when multiple first mounting beams 1 and second mounting beams 2 are provided, in order to further improve the structural strength and operational stability of the auxiliary installation fixture, and thus improve the auxiliary installation effect of the shock absorber 100, the auxiliary installation fixture in this embodiment also includes a second connecting beam (not shown in the figure). The two ends of the second connecting beam are respectively connected to two adjacent first mounting beams 1. That is, the second connecting beam, like the first connecting beam 6 mentioned above, allows multiple first mounting beams 1 to be connected through the second connecting beam, thereby improving the structural strength and operational stability of the auxiliary installation fixture, and thus improving the auxiliary installation effect of the shock absorber 100. It should be noted that the specific number of second connecting beams varies depending on the specific number of first mounting beams 1. Figures 1 to 4For example, when there are two first mounting beams 1, only one second connecting beam is provided to connect the two first mounting beams 1 respectively. Alternatively, when there are three first mounting beams 1, two second connecting beams are provided, each located between two adjacent first mounting beams 1 for connection. Further details are omitted here. Additionally, the specific connection method between the second connecting beam and the first mounting beam 1 can be an integrated connection, a detachable connection, etc. Taking an integrated connection as an example, the two ends of the second connecting beam can be welded to two adjacent first mounting beams 1 respectively. Taking a detachable connection as an example, the two ends of the second connecting beam can be connected to two adjacent first mounting beams 1 respectively using multiple bolts, pins, etc. These are all adaptive choices made by those skilled in the art based on actual usage requirements, and are not limited in detail here.

[0049] Furthermore, as an option, such as Figure 2 As shown, in the direction perpendicular to the frame 200, the first connecting beam 6 and the first mounting beam 1 are connected to the second mounting beam 2 at intervals, and the first connecting beam 6 is located between the first mounting beam 1 and the frame 200.

[0050] It is understandable that when both the first connecting beam 6 and the first mounting beam 1 are connected to the second mounting beam 2, their installation positions do not coincide in the direction perpendicular to the frame 200. Figure 2 As shown, in the direction perpendicular to the frame 200, the first connecting beam 6 and the first mounting beam 1 are sequentially and intermittently connected to the second mounting beam 2, and the first connecting beam 6 is located between the first mounting beam 1 and the frame 200. Thus, when the first mounting beam 1 is connected between the second mounting beam 2 and the middle bracket 300, the first connecting beam 6 is connected to other positions on the second mounting beam 2 except for the connection position of the first mounting beam 1. This ensures that the area on the second mounting beam 2 where the first mounting beam 1 is connected is different from the area where the first connecting beam 6 is connected, thereby avoiding stress concentration on the second mounting beam 2, ensuring the connection effect of the first connecting beam 6 and the first mounting beam 1 to the second mounting beam 2 respectively, and improving the structural stability of the auxiliary installation fixture.

[0051] Furthermore, as an option, such as Figure 2 As shown, in the direction perpendicular to the frame 200, the first connecting beam 6, the trolley beam 3 and the first mounting beam 1 are connected to the second mounting beam 2 at intervals, and the trolley beam 3 is located between the first connecting beam 6 and the first mounting beam 1.

[0052] It is understandable that when the first connecting beam 6, the first mounting beam 1, and the trolley beam 3 are all connected to the second mounting beam 2, their installation positions do not coincide in the direction perpendicular to the frame 200. Figure 2As shown, in the direction perpendicular to the frame 200, the first connecting beam 6, the trolley beam 3, and the first mounting beam 1 are connected to the second mounting beam 2 at intervals, with the trolley beam 3 located between the first connecting beam 6 and the first mounting beam 1. Therefore, the areas on the second mounting beam 2 where the first connecting beam 6, the trolley beam 3, and the first mounting beam 1 are connected are all different, thus avoiding stress concentration on the second mounting beam 2, ensuring the connection effect of the first connecting beam 6 and the first mounting beam 1 with the second mounting beam 2, improving the structural stability of the auxiliary mounting fixture, and is worth noting. It is worth mentioning that the first connecting beam 6 and the first mounting beam 1 are respectively located on both sides of the trolley beam 3 and connected to the second mounting beam 2. This means that when the trolley 4 drives the lifting sling 5 and the shock absorber 100 to move on the trolley beam 3, the first mounting beam 1 is connected to the frame 200 at one end of the second mounting beam 2, while the first connecting beam 6 is reinforced to the other adjacent second mounting beam 2 at the other end of the second mounting beam 2. This ensures the force balance of the second mounting beam 2 during operation, thereby ensuring the structural stability of the auxiliary installation tooling and the auxiliary installation effect.

[0053] As an option, such Figures 1 to 4 As shown, the auxiliary installation fixture also includes a third installation beam 7, one end of which is connected to the middle bracket 300, and the other end of which is connected to the trolley beam 3.

[0054] It is understandable that, in order to further improve the connection stability of the trolley beam 3, the auxiliary installation fixture in this embodiment also includes a third installation beam 7. One end of the third installation beam 7 is connected to the middle bracket 300, and the other end of the third installation beam 7 is connected to the trolley beam 3. The third installation beam 7 further improves the connection effect between the trolley beam 3 and the middle bracket 300, thereby improving the operational stability of the auxiliary installation fixture. It should be noted that the specific connection method between the third installation beam 7 and the middle bracket 300 and the trolley beam 3 can be an integrated connection, a detachable connection, etc. For example, the third installation beam 7 can be connected between the trolley beam 3 and the middle bracket 300 by multiple bolts, pins, etc., which will not be described in detail here.

[0055] Furthermore, as an option, such as Figures 1 to 6 As shown, the trolley beam 3 is an I-beam.

[0056] It is understandable that the trolley beam 3 is an I-beam, meaning that the trolley beam 3 has an "I"-shaped cross-section. This design ensures that the trolley beam 3 meets the lightweight requirements while achieving a large flexural section modulus with minimal material. This is because the "I"-shaped cross-section of the I-beam provides excellent torsional resistance, thus ensuring that the trolley beam 3 has excellent bending resistance. Furthermore, it is worth mentioning that... Figure 5As shown, the two sides of the I-beam naturally form concave track grooves, allowing the two rows of pulleys of the trolley 4 to smoothly abut and move, achieving reliable guidance and load-bearing. Of course, the trolley 4 can also move by setting a slide rail on the trolley beam 3. However, in this embodiment, the trolley beam 3 is preferably set as an I-beam, which can provide track grooves through the structure of the profile with an "I"-shaped cross-section, ensuring structural cost. It should also be noted that the trolley 4 is existing technology, and it can store and deploy the sling 5, thereby driving the shock absorber 100 to rise or fall. Detailed examples and limitations are not provided here. When the trolley beam 3 has an I-beam cross-section, the trolley 4 can have two rows of pulleys symmetrically arranged.

[0057] It should also be noted that the second mounting beam 2 can also be an I-shaped profile, thereby improving the structural strength and performance of the second mounting beam 2. Of course, the first mounting beam 1, the first connecting beam 6, the second connecting beam, and the third mounting beam 7 can also be I-shaped profiles, without being limited in detail here. In addition, it is worth mentioning that the specific materials of the first mounting beam 1, the second mounting beam 2, the trolley beam 3, the first connecting beam 6, the second connecting beam, and the third mounting beam 7 can be adapted by those skilled in the art according to actual usage requirements. For example, high-strength structural steel profiles can be used, more specifically, Q355D low-alloy high-strength structural steel, Q345 low-alloy high-strength structural steel, etc., which all have high strength, good toughness, and resistance to low-temperature impact, and can better withstand the movement of the lifting slings 5 ​​and the shock absorber 100, thereby assisting the shock absorber 100 in safe and stable installation.

[0058] Furthermore, the present invention also provides a method for using an auxiliary installation fixture, the steps of which include:

[0059] S1. The trolley beam 3 is connected to the middle bracket 300 via the first mounting beam 1, and the trolley beam 3 is connected to the frame 200 via the second mounting beam 2.

[0060] S2. Slide the trolley 4 onto the trolley beam 3;

[0061] S3. Connect one end of the sling 5 to the pulley 4, and connect the other end of the sling 5 to the shock absorber 100;

[0062] S4. Move the shock absorber 100 to the target installation position of the SCE920 engine assembly by using the pulley 4 and perform the installation operation.

[0063] It is understood that in step S1, the trolley beam 3 is specifically connected to the middle bracket 300 through the first mounting beam 1, and the trolley beam 3 is connected to the frame 200 through the second mounting beam 2, thereby completing the fixation of the trolley beam 3.

[0064] In step S2, the trolley 4 is specifically slidably mounted on the trolley beam 3, so that the trolley 4 can move on the trolley beam 3.

[0065] In step S3, one end of the sling 5 is connected to the pulley 4, and the other end of the sling 5 is connected to the shock absorber 100, thereby completing the hoisting of the shock absorber 100.

[0066] In step S4, the shock absorber 100 is moved to the target installation position of the engine assembly by the pulley 4, and then the shock absorber 100 is installed.

[0067] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
